Using this Excel template: Data chart for BUS520 SLP 2, do the following:

Calculate the MAPE for Year 2 Linear Regression forecast (use the first spreadsheet tab labeled “Year 2 Forecast – MAPE”).

Calculate forecasted sales for Year 2 using SES (use the second spreadsheet tab labeled “SES – MAPE”). Use 0.15 and 0.90 alphas.

Compare the MAPE calculated for the LR forecast (#1 above) with the MAPEs calculated using SES.

Then write a report to your boss in which you discuss the results
obtained above. Using calculated MAPE values, make a recommendation
concerning which method appears to be more accurate for the Year 2 data:
SES or Linear Regression.
